abstractText | We investigated the induction of ornithine decarboxylase during liver regeneration after partial hepatectomy in IRS-1-deficient mice. There were no significant differences in ODC activity or the time course of changes in ODC activity between IRS-1-deficient mice and wild-type mice. PI 3'-kinase activity showed similar increases in both groups of mice. Furthermore, ODC induction in IRS-1 transfected CHO cells was studied after stimulation by addition of FCS. The maximal ODC activity was 2.5-fold greater in IRS-1-transfected CHO cells than in control CHO cells. Our results suggest that the IRS-1 pathway may be involved in ODC induction. The absence of a difference in ODC and PI 3'-kinase activity in the regenerating liver between IRS-1-deficient mice and wild-type mice may have been related to the compensatory effects of IRS-2/pp190 [Araki et al.
